Clone K112-91 (RUO)

Multicolor flow cytometric analysis of Bcl-6 expression in mouse B lymphocytes (Middle and Right Panels). BALB/c mouse mesenteric lymph node cells were stained with APC Rat Anti-Mouse B220 (Cat. No. 553092/561880), PerCP-Cy™5.5 Rat Anti-Mouse CD4 (Cat. No. 550954/561115), FITC Hamster Anti-Mouse Fas/CD95 (Cat. No. 554257), and BD Horizon™ V450 Rat Anti-Mouse IgD (Cat. No. 560869) Abs. Cells were washed, resuspended in RPMI with 10% FBS, and fixed with BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049). Cells were permeabilized with BD Phosflow™ Perm/Wash Buffer I (Cat. No. 557885), followed by intracellular staining with BD Horizon™ PE-CF594 Mouse Anti-Bcl-6 antibody (Cat. No. 562401). A two-color flow cytometric dot plot shows the expression of IgD versus Fas/CD95 by B cells identified as CD4-B220+ from gated events with the forward and side light-scatter characteristics of intact lymphocytes (Middle Panel). Germinal center (GC) B cells were identified as Fas/CD95-positive B cells that expressed low levels of IgD (IgDloCD95/Fas+) whereas non-GC B cells primarily expressed intermediate to high levels of IgD and little or no CD95/Fas. Histograms (Right Panel) derived from gated cell subsets show intracellular Bcl-6 staining levels for mouse GC B cells (solid line) and non-GC B cells (dashed line). Flow cytometry was performed using a BD™ LSR II Flow Cytometer System.

Flow cytometric analysis of Bcl-6 expression in Ramos cells (Left Panel). Human Ramos cells were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655) and permeabilized with BD Phosflow™ Perm Buffer III (Cat. No. 558050) followed by intracellular staining with either BD Horizon™ PE-CF594 Mouse Anti-Human Bcl-6 antibody (Cat. No. 562401, solid line histogram) or a BD Horizon™ PE-CF594 mIgG1, κ Isotype Control (Cat. No. 562292; dashed line histogram). Flow cytometric fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of intact cells. Flow cytometry was performed using a BD™ LSR II Flow Cytometer System.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon™ PE-CF594 under optimum conditions, and unconjugated antibody and free PE-CF594 were removed.

Product Notices

This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
An isotype control should be used at the same concentration as the antibody of interest.
Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Antibody Details

K112-91

The K112-91 monoclonal antibody specifically binds to Bcl-6. Bcl-6 was first identified as a proto-oncogene frequently deregulated by chromosomal translocations in non-Hodgkin B-cell lymphomas. It is a nuclear transcriptional repressor of the BTB/POZ zinc-finger family of transcription factors. In addition to its roles in cancer, Bcl-6 plays important roles in the differentiation of normal cells including B cells, thymocytes, CD4+ or CD8+ T cells. Bcl-6 is highly expressed in germinal center B cells, where it promotes the germinal center reaction by inducing proliferation and inhibiting the DNA-damage response. Bcl-6 has been identified as a key factor in promoting the differentiation of CD4+ follicular T helper (Tfh) cells that are involved in promoting germinal center formation and providing help to B cells. The interplay of Bcl-6 and another transcriptional repressor, Blimp-1, is thought to be critical in defining the results of both B-cell and T-cell differentiation.

This antibody is conjugated to BD Horizon PE-CF594, which has been developed exclusively by BD Biosciences as a better alternative to PE-Texas Red®. PE-CF594 excites and emits at similar wavelengths to PE-Texas Red® yet exhibits improved brightness and spectral characteristics. Due to PE having maximal absorption peaks at 496 nm and 564 nm, PE-CF594 can be excited by the blue (488-nm), green (532-nm) and yellow-green (561-nm) lasers and can be detected with the same filter set as PE-Texas Red® (eg 610/20-nm filter).

Format Details

PE-CF594

BD Horizon™ PE-CF594 dye is a part of the BD PE family of dyes. This tandem fluorochrome is comprised of a R-Phycoerythrin (PE) donor that has excitation maxima (Ex Max) of 496-nm and 566-nm and an acceptor dye with an emission maximum (Em Max) at 615-nm. PE-CF594, driven by BD innovation, is designed to be excited by the blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and detected using an optical filter centered near 615 nm (e.g., a 610/20-nm bandpass filter). The donor dye can be excited by the Blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and the acceptor dye can be excited by the green (532-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
